Nano experts needed...

Id check River City aquatics to see if they carry them

Thanks for the replies. Somehow I already knew the 400w would be too much for the 29g. I just needed to hear it from someone else ;)

I do plan to keep SPS in the nano. I may utilize at least one of the 400w pendants over an SPS grow out tank. So now my question is this—should I start with the 250w and adjust the height of the pendant over the tank as needed? I would hate to start at 150w and then find out I actually need a 250w for the SPS then spit out more cash for the upgrade.

How many of you keep SPS in your nanos and what is your setup?

You could use a nuetral density filter over the glass on the 400watt MH to cut down the amount of light. Heat may still be an issue. You can find a large Neutral density filter at a photo store specializing in studio lighting. It would only run you about $15 or so for an 18"x24" sheet.

P.S. this would not change the color of the light ND filters are designed to be colorless.

I have a 29g Biocube w/1 150w HQI. I run an open top and have no heat issues. My tank is
overstocked w/ 6-fish and about 26-corals witch 15 are sps.The Biocube has good surface
skmming when you open the area between chamber 1 and chamber 2 witch will increase water flow. I do plan on a step up to 250w HQI because the light doesn't cover the tank very well. The 150w pod sets about 4-5 in above the water witch gives me 6in to top of my sps corals. I have found that most sps are raised in 250w or higher and the colors don't quite
match the mother colonies when a 150w is used. River city has alot of Biocubes in stock
aswell as AquaTek,but Horizon when he has them are $100 less for tank and stand combo.

The 150W should be plenty of lighting for your bio cube. You also wouldn't have to worry som much about the heat.

I would say the more you skim, the better, haha.
